    The OP was taking a math shortcut, like using 360 for calculating VA for a 3 phase load on a 208Y/120 source.

    And the 415V?
    Still as thick as two short planks.

    What the heck is this? Nothing to do with 240D/120V 3 phase calculation.

    Never mind- I was replying to Besoker. A 480 volt high leg is 416- double that of 208. But since the 415 in question is 3 phase, I was wrong.

    Yes, but the OP does not have a wye secondary.

    A 240V wye would be uncommon for most typical applications because unshown in that graphic is the center point ground connection and one would get 139V for L-N(G), Not very useful for receptacles and such.

    And please please no one bring up an ungrounded wye, my little brain cannot handle it.
